With major expansion plans and new products on the way, Blue Bottle Coffee, the Bay Area’s fast-growing gourmet roaster, has landed an additional $25.75 million in funding from some high-powered people in the tech world.

The new round of funding, first reported on Re/code, comes from Instagram co-founder Kevin Systrom and Twitter’s Evan Williams, among others, as well as a group of mutual funds and investors from Morgan Stanley Investment Management. It comes only two years after the Oakland-based artisan coffee chain raised $20 million from a number of notable firms that include Google Ventures, Index Ventures and True Ventures.

With the infusion of cash, founder James Freeman said Blue Bottle Coffee will be able to execute on its big expansion plans, which include building new cafes in Oakland, Palo Alto, Los Angeles, Manhattan and Brooklyn, where it recently signed a number of leases.

The company also has plans to open a research and development facility to test recipes and processes throughout the entire coffee chain, including green coffee, roasted coffee and food.

Blue Bottle said it will be working on sustainable packaging so that its coffee can be sold in bags and taken home and also plans to release a bottled iced coffee drink soon.

In a note on its website about the sudden cash flow, Blue Bottle assured its loyal customers and fans that the company will not change, and will stay committed to its founding values of “deliciousness, hospitality and sustainability.”
